Duplicate meetings due to multiple locations

[MinhxNguyen7]

Original: AntAlmanac/#257

When a section has more than one meeting time, the response will have multiple meetings with the same days and times but different buildings. I'm not sure whether you should modify the API, make a different endpoint, or tell me to stuff it, but I think it should be fixed on the API end.

Reproduction

1. Query /rest/v0/schedule/soc for any course that has multiple locations, e.g., EECS 170LB.
2. Look at the meetings array.
